BALL COCK.

Application filed May 4, 1927. Serial No. 188,759.

The present invention rclatesto improve ments in ball cooks for use 1n flush tanks and has for its principal. object to provide a structure which may be readily assembled or disassembled and which will furthermore at all times bepositive and efficient inv its operation.

One of the important objects of the present invention is to provide a ball cock which will eliminate the necessity of having to use the conventional thumb screws and the like such as are now generally used in ball. These" thumb screws and the like are ob ectionable cock structures now on the market.

in that the same will corrode and break off. Furthermore by provid ng a ball cock structure such as is embodied 1n the present invention, the proper fiowof thewater' through the intake pipe and the discharge of thewater therefrom into the flush tank can be more easily attained in a positive and cilicient manner.

A further object is to provide a ball cock of the above mentioned character which. is

- simple in construction, inexpensive, strong and durable andgfurther well adaptedto the purpose for which it is designed.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawing.

In the accompanying drawing wherein like reference characters indicate corresponding parts throughout. the same 2 Figure 1 is a vertical sectional view through the ball cock embodying my invention, and

Figure 2 is a top plan view showing the pivoted end of the float, rod or lever and supporting means therefor.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates an enlarged supply pipe which extends through a suitable opening provided therefor in the bottom of the flush tank, not.

' shown, and has communication at its lower end with a source of water supply, not shown, in the conventional manner. This pipe is threaded for receiving thereon the lock nut 2 whereby the same may be properly supported in the bottom of the flush.

tank.

This pipe or head 1 is formed at its upper end with an internally threaded neck 3 which communicates with the top of the head or pipe 1 for. receiving the lower 6X; ternally threaded end of a vertically extending intake water pipe or tube l in the manner clearly shown in Figure 1.

An internally threaded socket 5is formed on one side of the neck portion 3 of the head or pipe 1, and the upper face of: the connection wall between the neck and the socket is inclined as shown at 6. .The pur :pose of this socket is to provide a meansfor from to provide an annular water outlet chamber 10. For the purpose of properly spacing the outer pipe 9 withfrespect to the inner pipe 4:, the outer pipe is formed with the inwardly projecting .protuberances 11, in the manner clearly shown in the drawing, and the same are located; adjacent the upper and lower ends of the outer pipe. This outer pipe 9 extends from the upper end of the main intake pipe 4 to a point above the neck 3 so that the water which passes upwardly through the pipe land is discharged from the upper end thereof into the chamber 10 will pass into the flush tank, not shown,

through the lower end of the outer pipe 9 v for the purposeof refilling the flush tank.

The upper end of this outer pipe 9 is externally threaded for receiving thereon the I cap member 12 and the closed upper end 13 of this cap member is spaced from the upper end. of the main intake pipe l and the outer-pipe 9 to provide a chamber 14' in the manner as also clearly shown in Figure 1. f

Arranged within the chamber 14 is the valve 15, the same being preferably formed from rubber .and being in the form of a disc. This valve cooperates with theupper discharge endof the main intake pipe A to v I close the sameand prevent water fromlbeing discharged. into the chamber 10 when th flush tank is'filled to the proper height. A stem 16 extends upwardly from the central portion of the disc valve through a suitable opening provided therefor in the closed upper end 13 of the cap member 12. The upper end of this stein terminates in a hook 17. I

A refill tube 18 extends from the outer side of the auxiliary intake pipe 7 at a pointadjacent the upper end thereof, and is adapted to extend into the overflow pipe of the flush valve (not shown) for the purpose well known in the art; A plug 19 is removably secured within the upper open end of the auxiliary intake pipe 7 and the upperportion oi'thisplug is flattened or reduced as indicated at 20, and a shoulder 21 will be formed on each side of the flattened upper end portion 20 at its juncture 'with the plug 19. Thisshoulder is slightly inclined to provide imeans for supporting the arms of the il -shaped member designated generally by the numeral 22. This U-e shaped'meinber has its arms 23 and 2 1 disposed on opposite sides of the flattened upper end porti0n2O of the plug 19 and the outer ends of these arms are disposed on opposite sides of the hook shaped upper end 17 of the stem 16 in the manner clearly shown in Figure 2. I

Asocket 25 is formed on tlie closed end of this Li-shaped member 22 for receiving one end of the float rod or lever 26 which carries on its outer end the liollowfloat 27. 4

A pin28 extendsthrough suitable registering slots provided therefor in theouter end portions of the arms 23 and 2st of the Ushaped member 22 and theintermediate portion ofthis pin-is disposed beneath the hook 17 for cooperation therewith in the manner clearly shown in the drawing.

The tube 9 is slidably 'supported'over the main intakepipe 4 by reason of thecap "12 and tlieliook and pin connection described above so'that said pipe 9 will move vertically on the pipe 4 simultaneously with the cap in a manner readily obvious from the .construction shown.

The cap 12 is. connectedion' the upper end oftheslidable tube 9 whereby to pro-' vide a unitary structure and the dis'c'valve 15 is held against the under'sideolt' thetop of the cap due to the weight of the slidable tubeand said cap and furthermore the tube 9 is maintained in a raised position so that the disc valve'is out of en agement with the upperend of the main intake pipe by the weight of the float carrying member when the water in the flush tank'is at a predetermined level, andmanifestly when this float carrying member rises, the, pivoted end of said' member will'move downwardly to effect a downward sliding movement of the tube 9 on 'thepipe t'so that the discvalve will be brought into engagement with the upper end of themain intake pipe.

Also forming an important part of the the flush tank will enter theinletopening 8 formed in'the lower end of the auxiliary intake pipe 7 and pass upwardly therethrough andwill be discharged out through and 2eioi' the -Ushaped member 22, and a registering opening in the flattened upper end portion 20 of the plug 19 whereby to provide a fulcrum for the floatrodand the float carried thereby. This fulcrum is designated by the numeral 30,, and as clearly shown in Figure 2 of the drawing. The other end of the wireis also disposed lat orally in the same direction as the fulcrum forming portion 30 and extends across the rear poruionof the U-shaped' member 22 and is then disposed downwardly and thence inwardly whereby to form a spring lip 31 whichnormally bears against the rear end or socket 25 of the o -shaped member.

The operation of my improved ball cock may be briefly stated as follows:

lVith the parts arranged as shown in Figure 1 of the drawing, the valve 15 is raised out of engagement with the upper end of the main intake pipe 4 and water will flow upwardly through the pipe 4 and will be discharged out through the upper end thereofxinto the chamber 14 then into the chamber 10 Where the water wilhflow into the flush tank and 'a certain quantity of the water in the 'relillpipe 18 intothe upper portion of the flush tank, not shown.

As the flush tank becomes filled, the float 27 will rise upwardly in the conventional manner and the U-shaped member'22 will swing on its fuloruin BO'and as the outer :ends of the arms 0'5 the U-shaped member are operatively connected to the stem of the Valve, said valve will be moveddownwardly into engagement with the upper discutting off the water from entering the chamber'lO. 7 When I the water in the flush tank is empty, the float will descend and consequently swing the outer ends of the arms of the U-shaped member 22 upwardly thus raising the valve to an open position -wh'ere-- by water. will again be permitted to flow downwardly through the chamber 1O for the purpose of refillingthe flush tank.

Itwillthus be seen, from the foregoing charge end of themain intake pip'e-e thus description thatlhave provided a'ball cock for flushtanks which will at all times be positive and eflicient in its operation, and furthermore the simplicity of my devi'ce enables the part to be readily "andeasily accessible and the devicemay be quickly assembled or disassembled without any difli the present invention may be manufactured at a very low cost and will also be strong and durable.
